Target Condition - Class 1,2,3（⽬标条件 - 1,2,3级）
• Free of nicks and tears. Minimum edge to conductor spacing
maintained.
• The trimmed edge of the flexible printed board or the flexible
section of the finished rigid-flex printed board is free of burrs,
nicks, delamination, and tears.
• 无缺口和撕裂。满足板边到导体的最小间距。
• 挠性印制板或已完 工的刚挠印制板挠性段的裁切边缘无毛
刺、无缺口、无分层且无撕口。
Acceptable - Class 1,2,3（可接受条件 - 1,2,3级）
• No nicks, burrs or delamination in excess of that specified in the
procurement documentation.
• No tears in Type 1 or Type 2 flexible printed boards.
• No tears in the flexible portion of Type 3 or Type 4 flexible
printed boards.
• Nicks and tears that occur as a result of tie-in tabs to facilitate cir-
cuit removal as AABUS.
• Edge to conductor spacing of the flexible portion is within
requirements specified on the procurement documentation.
• Nicks or haloing along the printed board edges, cutouts, and
unsupported holes of the rigid portion of a rigid/flex printed
board, providing the penetration does not exceed 50% of the dis-
tance from the edge to the nearest conductor or more than 2.5 mm
[0.0984in], whichever is less.
• 缺口、毛刺或分层没有超过采购文件规定。
•1型和2型挠性印制板中无撕口。
•3型和4型挠性印制板的挠性段无撕口。
• 由于便于拆除电路连接头产生的缺口和撕口由供需双方协商
确定。
• 挠性段板边到导体的间距在采购文件规定的要求范围内。
• 沿印制板板边、切割和刚挠性印制板刚性段上非支撑孔允许
有缺口或晕圈，只要不超过板边到最近导体的距离的50%，
或不超过2.5mm[0.0984in]，取两者中的较小值。
Acceptable - AABUS（可接受条件 - 由供需双⽅协商确定）
• When nicks and tears occur as a result of tie-in tabs to facilitate
circuit removal, the extent of these imperfections does not exceed
the requirements agreed to by user and supplier.
• 当缺口和撕口是由于为便于拆除电路由连接头而产生时，这
些瑕疵的程度未超过由供需双方协商确定的要求。

A fold mark is characterized by bending in a sharp angle as shown in Figure 4112a. A bend mark is characterized by a bend whose radius is
an obtuse angle, as shown in Figure 4112b.
折叠痕迹是指如图4112a所示的以锐角角度弯曲造成的痕迹。弯曲痕迹是如图4112b所示的弯曲半径为钝角造成的痕迹。
